DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1:

[0029] Please see attached Figure 1 - Attachment Figure 8 The embodiment of the present invention provides an auxiliary exercise device for music rhythm training, including a frame 1, a top plate 3 is fixedly connected to the top of the frame 1, a mounting frame 2 is installed on the rear side of the top of the top plate 3, a speaker 7 is installed on the bottom of the rear side of the frame 1, a sound expansion board 801 is fixedly connected to the middle of the rear side of the frame 1, a plurality of sound expansion holes 802 are opened inside the sound expansion board 801, two columns 803 are fixedly connected to the rear side of the top plate 3, a guide rod 804 is fixedly connected to the inside of the column 803, and a second elastic sleeve is provided on the outside of the guide rod 804. Spring 805, the outside of the guide rod 804 is slidably connected to the support plate 806, and a paintbrush 807 is installed on the top of the support plate 806. Sound is emitted through the speaker 7. The sound is amplified by the sound amplification hole 802 and transmitted to the outer surface of the sound amplification board 801, and the sound amplification board 801 moves up and down, thereby driving the paintbrush 807 to move synchronously. The rear side of the mounting frame 2 is sequentially installed with a driving roller 601 and a driven roller 602, between which a cardboard 604 is connected, and the inner side of the driven roller 602 is installed with a torsion spring.

[0030] Specifically, the practitioner connects an external device (such as a microphone or an audio player) to the speaker 7 through the input interface 9. The speaker 7 sends out an audio signal, and the sound is transmitted and diffused through the sound amplification hole 802, thereby amplifying the propagation effect of the sound. The energy of the sound is transmitted through the sound amplification board 801, causing the sound amplification board 801 to vibrate up and down, and then transmitted to the support plate 806. The support plate 806 moves up and down due to the vibration of the sound, and drives the paintbrush 807 to draw a graphic on the cardboard 604 that is synchronized with the sound vibration. The driving roller 601 cooperates with the driven roller 602 to make the cardboard 604 move smoothly left and right, ensuring that the drawing of the paintbrush 807 can cover the entire surface of the cardboard 604. Through this audio-visual linkage method, learners can more intuitively perceive the rhythm and structure of music by observing the relationship between the graphics drawn on the cardboard 604 and the rhythm of the sound.

[0031] The guide rod 804 guides the support plate 806 to move up and down smoothly. The support plate 806 is connected to the guide rod 804 by sliding, ensuring that the movement track of the support plate 806 does not deviate, avoiding shaking or instability. The guide rod 804 provides support and fixing functions, helping the support plate 806 to maintain a vertical movement direction, ensuring that the paintbrush 807 can move evenly and stably on the paperboard 604.

[0032] The second spring 805 provides a restoring force to ensure that the support plate 806 can stably rebound to its original position when subjected to sound wave vibration or other external forces. The rebound force of the second spring 805 can also alleviate the excessive displacement caused by sound vibration, so that the support plate 806 can move smoothly and without losing control when moving in the reverse direction, thereby maintaining the stable movement of the paintbrush 807 and ensuring that the rhythmic pattern drawn on the paperboard 604 is clearly visible.

[0033] It also includes a wiping component, which is used to clean the writing on the outer surface of the cardboard 604. The wiping component includes a fixed block 605 fixedly connected to the rear side of the mounting frame 2, the bottom of the fixed block 605 is fixedly connected to a connecting plate 606, the inner sliding connection of the connecting plate 606 is connected to a movable plate 603, the outer side of the movable plate 603 is fixedly connected to a plurality of first springs 608, the other side of the movable plate 603 is fixedly connected to a word-clearing eraser 607, the outer surface of the word-clearing eraser 607 is in contact with the outer surface of the cardboard 604, and one end of the plurality of first springs 608 is fixedly connected to the inner wall of the connecting plate 606.

[0034] Specifically, when the wiping assembly is started, the connecting plate 606 drives the moving plate 603 to slide, and the outer surface of the cleaning wiper 607 contacts the surface of the cardboard 604. Due to the sliding connection design of the moving plate 603, the wiping assembly can move freely along a predetermined track on the surface of the cardboard 604. In this process, the elastic action of the first spring 608 ensures that the proper contact pressure is maintained between the cleaning wiper 607 and the cardboard 604. The restoring force of the spring ensures that the cleaning wiper 607 always remains on the surface of the cardboard 604, and automatically adjusts the force according to different external forces, thereby avoiding damage to the cardboard 604 caused by excessive wiping.

[0035] The material and design of the word cleaning eraser 607 enable it to effectively remove words or stains on the surface of the cardboard 604 without leaving marks or damaging the surface of the cardboard 604. The whole process can not only ensure that the surface of the cardboard 604 is clean and tidy, but also avoid damage or excessive wear of the cardboard 604 caused by improper wiping methods.

[0036] The technical effects are as follows:

[0037] Automatic adjustment of the force: Through the design of the first spring 608, the wiping component can automatically adjust the wiping force according to the different surface conditions of the cardboard 604, which can not only ensure the cleaning effect, but also avoid damage to the surface of the cardboard 604 caused by excessive pressure.

[0038] Stability and precision: The stable connection design of the fixed block 605 and the connecting plate 606 enables the wiping component to maintain a stable trajectory during movement, ensuring the accuracy of the wiping operation and preventing uneven cleaning effects due to unstable components.

[0039] Efficient cleaning: The design of the word eraser 607 can quickly and effectively remove the writing on the surface of the cardboard 604, and can maintain the cleaning effect for a long time, reducing the workload of manual intervention and repeated cleaning.

[0040] The top of the second spring 805 is fixedly connected to the bottom of the support plate 806, and the bottom of the second spring 805 is fixedly connected to the inner wall of the column 803. A display screen 11 is installed on the front side of the mounting frame 2, and the display screen 11 is used to display the image displayed on the paperboard 604 in real time.

[0041] The difference between the second embodiment and the first embodiment is that the present embodiment can provide special training for individuals who are undergoing piano training. The specific scheme is as follows:

[0042] A plurality of light guide columns 501 are fixedly connected to the outer surface of the mounting frame 2, and a contact button 502 is installed on the top of each light guide column 501, and the contact button 502 is used to control the start and stop of the light of the light guide column 501. An electric guide rail 505 is installed in the middle of the inner side of the mounting frame 2, and an electric slider 506 is installed on the outer side of the electric guide rail 505. A swing frame 503 is hinged on the outer side of the electric slider 506, and a movable groove 508 is opened on the inner side of the swing frame 503. A guide block 509 is slidably connected inside the movable groove 508, and an electric telescopic rod 507 is installed on the outer side of the electric slider 506. The output end of the electric telescopic rod 507 is rotatably connected to the outer surface of the guide block 509, and a pressing ball 504 is fixedly connected to the bottom end of the swing frame 503.

[0043] Specifically, the device combines electronic control, mechanical motion and photoelectric feedback technology to help practitioners master accurate rhythm in music rhythm and fingering training. By combining music frequency regulation with an electric control system, a trigger action is generated on the contact button 502 by pressing the ball 504, thereby achieving rhythm guidance and practice feedback. By controlling the cooperation of the electric slider 506 and the electric telescopic rod 507, the movement of the swing frame 503 is driven, and then the interaction between the pressing ball 504 and the contact button 502 is controlled, thereby achieving guidance and prompts on the music rhythm.

[0044] The user can input the rhythm frequency of the desired song through the operation panel 10, and the system will automatically adjust the movement speed of the electric slider 506 and the start and stop time of the electric telescopic rod 507 according to the input frequency. The input of the rhythm frequency will directly affect the execution speed of the internal control program of the device, thereby accurately adjusting the requirements of rhythm training.

[0045] When the operating system is set according to the frequency of the musical rhythm, the electric slider 506 will start to move along the electric guide rail 505. The moving speed of the slider is closely related to the rhythm of the music. The electric telescopic rod 507 is started at a specific node, driving the guide block 509 to slide along the inner wall of the movable groove 508, pushing the swing frame 503 to swing. The bottom end of the swing frame 503 is connected to the pressing ball 504, and the function of the pressing ball 504 is to press the contact button 502. At each set node, the pressing ball 504 will hit the contact button 502, activating the corresponding light guide column 501 to emit light. The appearance of light will indicate that the user presses the corresponding key at the corresponding moment, helping the practitioner to accurately grasp the rhythm and complete the key training. When the pressing ball 504 contacts the contact button 502 and activates the light guide column 501, the output end of the electric telescopic rod 507 will shrink, driving the guide block 509 to reset. At this time, the swing frame 503 and the pressing ball 504 will swing outward until the pressing ball 504 is no longer in contact with the contact button 502, completing a rhythm instruction. The electric slider 506 continues to run under the program control set by the PLC, completing the next rhythm guidance action, realizing a cyclic operation, and guiding the user to continuously perform music rhythm training.

[0046] An input interface 9 is provided on the outside of the speaker 7, and the input interface 9 is used to connect an external input device. A training piano board 4 is fixedly installed on the front side of the top of the top plate 3, and an operation panel 10 is installed on the top of the top plate 3, and the operation panel 10 is used to control the moving speed of the electric slider 506. The light guide 501 is powered by an external power supply, and the pressing ball 504 is in intermittent contact with the contact button 502.

[0047] Specifically, the input interface 9 is used to connect an external device, such as a music player, a computer or other audio source. Through this interface, the speaker 7 can receive an external audio signal and convert it into sound output. The types of input interface 9 include 3.5mm audio jack, USB port, Bluetooth or Wi-Fi connection. According to actual needs, the interface can support audio transmission in different formats to ensure high-quality input of audio signals.

[0048] Working principle: To use the device, first input the frequency of the music of the song according to the operation panel 10, and then adjust the running speed of the electric slider 506 and the start and stop time of the electric telescopic rod 507 accordingly;

[0049] At this time, as the electric slider 506 moves, when the electric slider 506 moves to a certain node, the electric telescopic rod 507 is started, thereby driving the guide block 509 to move along the inner wall of the movable groove 508, and further swinging the swing frame 503, and knocking the pressing ball 504 on the outer surface of the contact button 502. By pressing the contact button 502, the corresponding light guide column 501 is energized and emits light. The light corresponds to the piano keys on the outer surface of the training piano board 4, and at this time, the practitioner is guided to master the training rhythm of the music. With the pressing of the piano keys this time, the output end of the electric telescopic rod 507 shrinks, driving the guide block 509 to reset. At this time, the swing frame 503 and the pressing ball 504 swing outward until the pressing ball 504 is no longer in contact with the contact button 502 just now, and the electric slider 506 continues to move according to the program set by the PLC to realize the cycle operation;

[0050] In addition, the practitioner inserts the output interface of an external device such as a broadcasting microphone into the input interface 9, and plays the sound through the speaker 7. As the sound is broadcast, the sound will diffuse through the sound amplification hole 802 inside the sound amplification board 801, thereby amplifying the sound. The energy generated by the sound is transmitted to the support plate 806, and the support plate 806 moves up and down along the outer wall of the support plate 806. At this time, by starting the motor on the top of the driving roller 601, the paperboard 604 is driven to move evenly, and the vibration generated by the sound is painted on the paperboard 604 with a brush 807. In this way, through the combination of music and visual graphics, learners can understand the structure and rhythm of music more deeply through the audio-visual linkage, thereby improving the learners' musical rhythm.

[0051] In summary: the present invention, through the combination of music and visual graphics, can allow learners to more deeply understand the structure and rhythm of music through audio-visual linkage, improve the learners' musical rhythm, and at the same time, for piano practitioners, the user can press the corresponding keys according to the emitted light guide column 501 when playing to play the corresponding music, which can conveniently help practitioners master the rhythm of music training.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
